ADJUSTABLE SHADE-ROLLER.

Application filed June 28, 1919.

To all whom it may concern lie it known that I, EDWARD L. FLEMMING, acitizen of the United States, residing at Easton, in the county ofNorthampton and State of Pennsylmnia, have invented certain. new anduseful Improvements-in Adjustable Shade-Rollers, of which the followingis a specification,reference being had therein to the accompanyingdrawings.

This invention relates to a shade roller, and more particularly to anextensible roller that can be easily ad usted to fit windows or windowframes of different widths.

The object of the invention is the construction of an expansible rollerwhich is provided with simple and efficient means for allowing a shadeto be tacked or fastened to the roller throughout its length,irrespective as to the adjustment or length of the roller.

With this and other objects in view, my invention comprises certainnovel constructions, combinations, and arrangements of parts as will behereimifter specifically de scribed, illustrated in the accompanying rlrawings, and more particularly pointed out in the appended claims.

In the drawings,

Figure 1 is a longitudinal, sectional view of a roller constructed inaccordance with the present invention, showing a shade attached thereto.

Fig. 2 is a longitudinal, sectional view of the roller, with the shaderemoved, showing the sliding parts of the roller somewhat closelytogether to illustrate more clearly the adjustment or expansibleprinciple of the roller.

Fig. 3 is a perspective view of the piston device of the roller.

Fig. 4 is a sectional view of the hollow, primary section of the roller.

Referring to the drawings by numerals, 1 designates the hollow, primarysection, and 2 the piston device.

The hollow, primary section is provided with a wooden plug or closure 3extending into the section 1 at 4, and. a tack 5, extending throughaperture 6, serves to hold the plug in the outer end of easing orsection 1, and also serves to partly attach the shade 6 to the roller(Fig. 1). A suitable bracket pintle 7 is attached to plug 3. The casingor section 1 is provided. with a plurality of apertures 8 intermediateits ends, preferably near its middle, and said section is also providedwith an aperture 9.

Specification of Letters Patent.

Serial No. 307,312.

The piston device comprises a body 10, a primary piston 11 of a reduceddimension compared with body 10, and an auxiliary piston 12 is attachedto the outer end of the primary piston 11 by a flexible connection, cord13, for instance; the cord 13 is attached by a tack 1 1 to the extremeouter end of the piston 11, and said cord is attached by tack 15 to anend of the auxiliary piston 12.

Suitable means, as a coil spring, can be placed within the end 16,attached to the outer end of body 10, and to this extreme outer end 1.6is secured an ordinary pintle '17- to engage a bracket. I make nospecific claim to the means for rewinding my roller, as any means known.to the art may be uti lized in constructing my roller for rewind.- ingthe same.

The operation ofthe device is as follows: The auxiliary piston 12 isplaced in the hollow casing or section 1, and pushed i11- wardly by theouter end of the primary piston 11, the aliixiliary piston 12 beingpulled mitwardly by the flexible connection 1?, being attached to theprimary and auxjiliary pistons, so that the auxiliary piston 12 can beaccurately placed under the apertures 8, whereby tack 18 can be passedthrough the shade 6 and into the auxiliary piston (Fig. 1), affording anexcellent securing means for the tack; then the primary piston can beadjusted within the hollow section. 1 to obtain the desired length foraccommodating the roller to a given window or window frame. Severaladjustments of the piston device within the hollow section 1 can beobtained, hence making it possible to secure a number of adjustments ofthe roller to different size or width. windows. The auxiliary piston 12always affords an excellent foundation or fastening means for the tack18, whereby the shade 6 can be fastened securely throughout its width tothe roller, as a tack 19 is passed through the aperture 9 of the section1 and into the primary piston (Fig. 1), and tacks 20 are used to fastenshade 6 to the body of the piston device.

I have found from actual experience with my improved roller, that thedirect connecting of the auxiliary piston by a flexible means to theprimary piston produces a marked advantage in allowing the adjust mentof the piston device upon the hollow casing and affording satisfactorymeans for supporting tacks securely upon the metal portion or section 1of an cxpansible or extensible roller.

In carrying out my invention, 1 may find that certain minor changes oralterations will be desirable, and I reserve the right to make suchalterations or changes as shall appear to one prisinga body, a primarypiston secured to said body and being of a reduced size com- :pared withthe body, an auxiliary piston, a

flexible connection fastened near its ends to the contiguous ends oi theprlmary and auxiliary pistons, said primary and auxiliary pistonspositioned within the primary seetion, and fastening means extendingthrough the apertures of the primary section and into the primary andauxiliary pistons for securing the same in adjusted positions within theprimary section.

2. In a device of the class described, the combination of a hollowcasing or section, said section provided with an aperture near itscenter, a piston device including a body and a primary piston, saidprimary piston extending into the hollow section, an auxiliary piston insaid primary section, and means cooperating with said primary andauxiliary pistons for placing the auxiliary pistonbcneath orin alinement\viththe aperture of the primary section whenthe piston device isadjusted u'ponthe'primary section.

In testimony whereoii l. liereunt'o aifiix my signature.
